ABSTRACT

Compounds of formula I are provided  
                 
 
     as well as pharmaceutically acceptable salts and esters thereof, wherein R 1  to R 5 , n, m and A have the significance disclosed in the specification, and can be used for the treatment or prevention of arthritis, cardiovascular diseases, diabetes, renal failure, eating disorders and obesity.

BACKGROUND OF THE INVENTION

[0001] Neuropeptide Y is a 36 amino acid peptide that is widely distributed in the central and peripheral nervous systems. This peptide mediates a number of physiological effects through its various receptor subtypes. Studies in animals have shown that neuropeptide Y is a powerful stimulus of food intake, and it has been demonstrated that activation of neuropeptide Y Y5 receptors results in hyperphagia and decreased thermogenesis.

[0002] Therefore compounds that antagonize neuropeptide Y at the Y5 receptor subtype represent an approach to the treatment of eating disorders such as obesity and hyperphagia.

[0003] The current approach is aiming at medical intervention to induce weight loss or prevention of weight gain. This is achieved by interfering with appetite control, which is mediated by the Hypothalamus, an important brain region proven to control food intake. Herein, neuropeptide Y (NPY) has been proven to be one of the strongest central mediators of food intake in several animal species. Increased NPY levels result in profound food intake. Various receptors of neuropeptide Y (NPY) have been described to play a role in appetite control and weight gain. Interference with these receptors is likely to reduce appetite and consequently weight gain. Reduction and long-term maintenance of body weight can also have beneficial consequences on con associated risk factors such as arthritis, cardiovascular diseases, diabetes and renal failure.

[0353] Processes for the manufacture of compounds of formula I are an object of the invention.

[0354] The preparation of compounds of formula I of the present invention may be carried out in sequential or convergent synthetic routes. Syntheses of the invention are shown in the following Schemes. The skills required for carrying out the reaction and purification of the resulting products are known to those in the art. The substituents and indices used in the following description of the processes have the significance given above unless indicated to the contrary.

[0355] Compounds of general formula IH (R² means hydrogen) can be prepared according to scheme 1 as follows:

[0356] a) Bis amino derivatives IA, either commercially available or prepared from commercially available precursors by methods taught in the art, are mono-protected with a suitable protecting group (PG i.e. Boc, Fmoc , and the like), provided that PG has no adverse effect on the reaction or on the reagents involved in the synthetic route, by reaction of IA with preferably Boc₂O, preferably in the presence or the absence of a base such as triethylamine, diisopropylethylamine, and the like, preferably in the presence of a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: dichloromethane, chloroform, or dioxane, and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice. (literature: J. Med. Chem., 32(2), 391-6; 1989).

[0357] b) Thioureas can be prepared from suitable starting materials according to methods known in the art. The elaboration of the thiourea-moiety in ID starting from an amino functionality, like in IB can be affected by methods described in literature. For example mono-protected derivatives IB are condensed with benzoyl isothiocyanate in a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: dichloromethane, chloroform, or dioxane, and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield the protected urea derivatives IC. (literature: Organic Letters, 2(20), 3237-3240;2000). The urea derivatives IC are subjected to basic cleavage conditions such as. K₂CO₃ aq., and the like, in a solvent such as methanol, and the like, to liberate the urea functionality and access ureas ID. (for reaction conditions described in literature affecting such a reaction see for example: J. Med. Chem., 32(8), 1963-70; 1989).

[0358] c) The conversion of the liberated ureas ID to Dimethylaminomethylene-thioureido derivatives IE (R2 means hydrogen) was affected by reaction of derivatives ID with N,N-Dimethylformamide dimethyl acetal either neat or in a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: dichloromethane, chloroform, or dioxane, DMF and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield the protected urea derivatives IC. For reaction conditions described in literature affecting such a reaction see for example: Heterocycles, 11, 313-18; 1978.

[0359] d) Dimethylaminomethylene-thioureido derivatives IE can be converted to thiazole derivatives IF (R2 means hydrogen) by reaction of IE with α-bromoketones (a known compound or compound prepared by known methods. The source for α-Bromoketones employed is indicated as appropriate) in a solvent such as ethanol, and the like, in the presence or the absence of a base. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: dichloromethane, chloroform, or dioxane, methanol, ethanol and the like. There is no particular restriction on the nature of the base used in this stage, and any base commonly used in this type of reaction may equally be employed here. Examples of such bases include triethylamine and diisopropylethylamine, and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield the protected thiazole derivatives IF. For reaction conditions described in literature affecting such a reaction see for example: J. Heterocycl. Chem., 16(7), 1377-83; 1979. The resulting compound of formula IF is a compound of the present invention and may be the desired product; alternatively it may be subjected to consecutive reactions.

[0360] e) Cleavage of the protecting group PG such as Boc, Fmoc, and the like from thiazole derivatives IF to access free amines IG or various salts thereof, IF is in the case PG means Boc subjected to suitable reaction conditions like acidic cleavage. There is no particular restriction on the nature of the acid used in this stage, and any acid commonly used in this type of reaction may equally be employed here. Examples of such acids include: HCl, TFA, and the like in a solvent. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: dioxane, water, and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield thiazole derivatives IG. For conditions described in literature affecting the cleavage of a protecting group see for example: Protecting Groups, Kocienski, P. Thieme Verlag New York 1994.

[0361] f) Sulfonamides, amides, carbamates and ureas can be prepared from suitable starting materials according to methods known in the art. The conversion of the amino-moiety in IG to access sulfonamides, amides, carbamates and can be affected by methods described in literature. For example the conversion of the amine derivatives IG or their respective salts to access compounds of the general formula IH is affected by reaction of IG with suitable acid chlorides, sulfonyl chlorides, isocyanates, chloroformates, or carbonate esters (compounds known or compound prepared by known methods) respectively in a solvent like dichloromethane and in the presence or the absence of a base. There is no particular restriction on the nature of the solvent to be employed, provided that it has no adverse effect on the reaction or the reagents involved and that it can dissolve the reagents, at least to some extent. Examples for suitable solvents include: chloroform, or dioxane, THF, and the like. There is no particular restriction on the nature of the base used in this stage, and any base commonly used in this type of reaction may equally be employed here. Examples of such bases include triethylamine and diisopropylethylamine, and the like. The reaction can take place over a wide range of temperatures, and the precise reaction temperature is not critical to the invention. We find it convenient to carry out the reaction with heating from ambient temperature to reflux. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield thiazole derivatives IH.

[0363] a) Thioisocyanates can be prepared from suitable starting materials according to methods known in the art. The elaboration of the thioisocyanate-moiety in IIA (R³ means hydrogen) starting from an amino functionality, can be affected by methods described in literature. For example compounds of the general formula IB (PG for example Boc, Fmoc, and such like) are condensed with carbondisulfide, neat or in a solvent.

We find it convenient to carry out the reaction from 0° C. to heating to reflux temperature of the solvent. The time required for the reaction may also vary widely, depending on many factors, notably the reaction temperature and the nature of the reagents. However, a period of from 0.5 h to several days will usually suffice to yield the thioureido derivatives IIB.

Assay Procedures Cloning of Mouse NPY5 Receptor cDNAs

[0432] The full-length cDNA encoding the mouse NPY5 (mNPY5) receptor was amplified from mouse brain cDNA using specific primers, designed based on the published sequence, and Pfu DNA-Polymerase. The amplification product was subcloned into the mammalian expression vector pcDNA3 using Eco RI and XhoI restriction sites. Positive clones were sequenced and one clone, encoding the published sequence (see Borowsky, B., et al., Molecular biology and pharmacology of multiple NPY Y5 receptor species homologs, Regul. Pept. (1998) 75-76:45-53) was selected for generation of stable cell clones.

Stable Transfection

[0433] Human embryonic kidney 293 (HEK293) cells were transfected with 10 μg mNPY5 DNA using the lipofectamine reagent (Gibco BRL) according to the manufacturer's instruction. Two days after transfection, geneticin selection (1 mg/ml) was initiated and several stable clones were isolated. One clone was further used for pharmacological characterization.

Radioligand Competition Binding

[0434] Human embryonic kidney 293 cells (HEK293), expressing recombinant mouse NPY5-receptor (mNPY5) were broken by three freeze/thawing cycles in hypotonic Tris buffer (5 mM, pH 7.4, 1 mM MgCl₂), homogenized and centrifuged at 72,000×g for 15 min. The pellet was washed twice with 75 mM Tris buffer, pH 7.4, containing 25 mM MgCl₂ and 250 mM sucrose, 0.1 mM phenylmethylsulfonylfluoride and 0.1 mM 1,10-pheneanthrolin, resuspended in the same buffer and stored in aliquots at −80° C. Protein was determined according to the method of Lowry using bovine serum albumine (BSA) as a standard.

[0435] Radioligand competition binding assays were performed in 250 μl 25 mM Hepes buffer (pH 7.4,2.5 mM CaCl₂, 1 mM MgCl₂, 1% bovine serum albumine, and 0.01% NaN₃ containing 5 μg protein, 100 pM [¹²⁵I] labelled peptide YY (PYY) and 10 μL DMSO containing increasing amounts of unlabeled test compounds. After incubation for 1 h at 22° C., bound and free ligand are separated by filtration over glass fibre filters. Non specific binding is assessed in the presence of 1 μM unlabelled PYY. Specific binding is defined as the difference between total binding and non specific binding. IC₅₀ values are defined as the concentration of antagonist that displaces 50% of the binding of [¹²⁵I] labelled neuropeptide Y. It is determined by linear regression analysis after logit/log transformation of the binding data.

[0436] Results obtained in the foregoing test using representative compounds of the invention as the test compounds are shown in the following table: Compound IC₅₀ Example No. 1 5.4 nM 2-Fluoro-N-{3-[5-(pyridine-2-carbonyl)-thiazol-2- ylamino]-propyl}-benzenesulfonamide Example No. 140   6 nM 2-Methoxy-5-methyl-N-{3-[4-(2-methyl-benzoyl)- thiazol-2-ylamino]-propyl}-benzene sulfonamide

[0437] Compounds as described above have IC₅₀ values below 1000 nM; more preferred compounds have IC₅₀ values below 100 nM. Most preferred compounds have IC₅₀ values below 10 nM. These results have been obtained by using the foregoing test.

[0438] The in vitro assay published by D. Lachammer, et al., Reversal of NPY inhibition of forkelin-stimulated cAMP production, J. Biol. Chem. (1992) 267:10935-8, and M. H. Norman et al., J. Med. Chem. (2001) 44:2344-56, was used to confirm that the compounds of the present invention are antagonists of neuropeptide Y.

[0439] The compounds of formula I and their pharmaceutically usable salts, solvates and esters can be used as medicaments (e.g. in the form of pharmaceutical preparations which include pharmaceutically acceptable carriers which are therapeutically inert). The pharmaceutical preparations can be administered internally, such as orally (e.g. in the form of tablets, coated tablets, dragees, hard and soft gelatin capsules, solutions, emulsions or suspensions), nasally (e.g. in the form of nasal sprays) or rectally (e.g. in the form of suppositories). However, the administration can also be effected parentally, such as intramuscularly or intravenously (e.g. in the form of injection solutions).

[0440] The compounds of formula I and their pharmaceutically usable salts, solvates and esters can be processed with pharmaceutically inert, inorganic or organic adjuvants for the production of tablets, coated tablets, dragees and hard gelatin capsules. Lactose, corn starch or derivatives thereof, talc, stearic acid or its salts etc. can be used, for example, as such adjuvants for tablets, dragees and hard gelatin capsules.

[0441] Suitable adjuvants for soft gelatin capsules, are, for example, vegetable oils, waxes, fats, semi-solid substances and liquid polyols, etc.

[0442] Suitable adjuvants for the production of solutions and syrups are, for example, water, polyols, saccharose, invert sugar, glucose, etc.

[0443] Suitable adjuvants for injection solutions are, for example, water, alcohols, polyols, glycerol, vegetable oils, etc.

[0444] Suitable adjuvants for suppositories are, for example, natural or hardened oils, waxes, fats, semi-solid or liquid polyols, etc.

[0445] Moreover, the pharmaceutical preparations can contain preservatives, solubilizers, viscosity-increasing substances, stabilizers, wetting agents, emulsifiers, sweeteners, colorants, flavorants, salts for varying the osmotic pressure, buffers, masking agents or antioxidants. They can also contain still other therapeutically valuable substances.

[0446] In accordance with the invention the compounds of formula I and their pharmaceutically usable salts, solvates and esters can be used for the prophylaxis and treatment of arthritis, cardiovascular diseases, diabetes, renal failure and particularly eating disorders and obesity. The dosage can vary in wide limits and will, of course, be fitted to the individual requirements in each particular case. In general, in the case of oral administration a daily dosage of about 0.1 mg to 20 mg per kg body weight, preferably about 0.5 mg to 4 mg per kg body weight (e.g. about 300 mg per person), divided into preferably 1-3 individual doses, which can consist, for example, of the same amounts, should be appropriate. It will, however, be clear that the upper limit given above can be exceeded when this is shown to be indicated.
